HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 676,176, dated June 11, 1901. Application filed January '7, 1901. Serial No. 42,273. (No model.)

To @ZZ whom t may concern.:

n Be it known that we, JOHN W. CONWAY and JEEEMIAH MCCARTHY, citizens of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Heating Apparatus, fully described and representedin the following specification and the accompanying drawings, forming a part ofthe same.

This invention relates to a heating apparatus of such a form as to provide a means by which articles of food, dishes, &c., may be kept at a proper temperature in hotels, apartment-houses, flat-houses, dac., while the cooking of the food is taking place or for reheating the food after being cooked and when about to be used. In houses of the kind above referred to, especially in apartment-houses and Hat-houses, the cooking is to a great eX- tent now being done with gas-ranges or gasstoves, and it has been found that the means provided by said ranges or stoves for the reheating of food or heating dishes about to be used in a proper manner are limited to a great extent. The heat being a dry heat also tends to dry the food and also to crack and ruin the dishes.

The object of this invention, therefore, is to provide a constant relatively moist heat for the purpose above mentioned which will be readily accessible to persons desiring to use the same.

To this end the invention consists in a heating-receptacle suitably placed in a room, said receptacle containing a coil or coils of suitable piping through which hot water of a proper temperature is caused to circulate.

The object of the invention is also to arrange these receptacles or closets in the several apartments or floors of the house in which they are to be used in such a manner as to be simultaneously supplied with hot water from a boiler or other hot-water supply.

In the accompanying drawings, Figure l is a front elevation of one of the heating receptacles or closets, the door of the receptacle being open. Fig. 2 is a sectional plan view of same, taken on the line 2 2 of Fig. l. Fig. 3 is a diagrammatic sectional elevation of the several ioors of a house provided with the heating-receptacle.

Referring now to Figs. l and 2, Ais a heating receptacle or closet which may be of any preferred form and construction. The receptacle is provided with a door B, through which the articles to be heated are passed. Heating-coils O C C2, which may be of any form or size, but which are preferably of the form shown in Fig. 2, are supported one above the other inside the receptacle A on supports a, which are riveted or secured in any suitable manner to the lining a, of the receptacle. This lining may be of asbestos or other suitable material. Placed on the top of the coils O O' C2 are perforated trays D, preferably turned down at their ends so as to lap over the heating-coils and prevent the tray with `the articles to be heated from moving with respect to the heating-coils. The heatingcoils C O C2 are connected one to the other by vertical pipes c, thus providing a continuous circulation of water through all the coils. The coil C at the bottom ofthe receptacle is connected to a service-pi pe E by a connection c', and the coil C2 at the upper part of the box is connected to the pipeE bya connection c2. The pipe c' is provided with a cock l, and the pipe c2 is provided with a cock 2, whereby the supply of water from the service-pipe E to the coils C O C2 is stopped when the receptacle is not in use. The service-pipe E is provided with a cock 3, located between the pipes c c2 and which is closed when the coils in the receptacle A are to besupplied with water from the service-pipe E. 1

The operation of the apparatus is as follows: Referring to Fig. 3, assuming that the cocks 1 and 2 in the pipes c' c2 are open and the cock 3 in the pipe E closed, then the hot water will pass from the hot-water supply F through the pipe E, thence through pipe c to the coil C, thence to'eoil C' through vertical pipe c, thence to the coil C2 through a similar pipe c, and thence through pipe c2 to the service-pipe E. The water will then pass upward to the lioor above, where a similar heating-receptacle A is situated, thence in turn to the Hoor above, and so on until all of the receptacles have been in turn supplied with hot water. The water will then pass through the return-pipe F to the boiler F'. When it is necessary to cut 0E the water-supply to any one of the receptacles, the cocks 1 and 2 of IOO the pipes "cc'f will be closed and the cock 3 of the service-pipe E -opened, the section of pipe E between the pipesv c c2 acting as a by-passV for the passage of water to the next recep- 5 tacle. The connections to all the receptacles are vSimilar inconstruction in all the aparti ments.

What is claimed isl`. In a system of warming-closets, the coml 1o bination with a vertical riser-pipe, and areand connected with each other, an inlet con- 15 necting the lowest coil to the riser-pipe and an outlet 'connecting the highest coil 'to said` u J each receptacle to the said Vriser-pipe` above ris'gerpi'pe vabove 'the inlet. y

. i In a syst'einof warming-closets,the coni- 'ati`n,with a vertical lriser-pipe, and a rele for the reception of the articles to be e'd, of aplurality of Vcoils located within the receptacle in different horizontal Vplanes aridfconnected with each other, an inlet oon-v necting 'the lowest coil tothe riser-pipe, an

25 o` t connecting the highest coil to said riserve th'einlet,- and a cock in the riserpipe lbetweensaid inlet and outlet. l

3 Ina syste of warming-closets, the comfnfwith a Vertical riser-pipe, and a lrie-1 le for the reception of 'the articles to be rni'vejd, `of a pl uralit'y of coils located within the receptacle in different horizontal planes and connected with eachother, an inlet coinecting the lowest coil with the riser-pipe, an outlet connecting the highest coil to said riserpipe above the inlet, a cock in the riser-pipe between the inlet and outlet, andcocks in the inletand outlet respectively. i

4. In a system of warming-closets, the coinbination Vwith a vertical riser-pipe, and a plurality of receptacles for the reception of the articles to be warmed, said receptacles being located one above the other, of a plurality of coils. in each receptacle, said coils being located in different horizontal planes and connected with each other, an inlet connecting the lowest coil of eachreceptacle to the riserpipe', an outlet connecting the highest coil of its respective inlet, a pluralityof cocks -inthe riser-pipebetween the 'respective inlets and outlets, a boiler connected to the lowerend of theriser-pipe,and an uninterrupted returnpipe connecting the upper endof the 4riserpipe with the boil-er; l y
